Embodiment Construction

[0025] exist Figure 1 to Figure 6 exemplarily shows a first embodiment variant of the inflatable protective device according to the invention, while Figure 7 to Figure 11 A second possible embodiment variant of the inflatable protection device is shown.

[0026] Independent of the corresponding embodiment variant, an inflator protection device is proposed according to the invention for preventing damage, in particular when an airbag 1 is inflated by a gas generator 3 for a vehicle occupant restraint system. The inflatable safety device has at least one protective element 4, 4A, which is arranged in such a way that the protective element surrounds the folded airbag and / or the gas generator connected to the airbag at least in sections, so that at least the airbag 1 The inflatable area is covered at least partially at the ends.

[0027] Figure 1 to Figure 6 A first embodiment variant of the inflatable safety device is shown, in which the protective element 4 is of dimension...

Abstract

An inflatable protective device for preventing damage when an airbag (1) is inflated by means of a gas generator (3) is proposed, wherein at least one protective element (4, 4A) is arranged in such a way that the The protective element (4, 4A) surrounds, at least in sections, the folded airbag (1) and / or the gas generator (3) connected to the airbag (1). Furthermore, an airbag module is proposed which has an airbag (1) and a gas generator (3) as well as an inflatable protection. Furthermore, a vehicle occupant restraint system with an airbag module is claimed.

Description

technical field [0001] The invention relates to an inflatable protection device for a vehicle occupant restraint system for preventing damage when an airbag is inflated by a gas generator. Background technique [0002] Vehicle occupant restraint systems are known to include an inflatable airbag, such as a side airbag, and a gas generator for inflating the airbag when activated, which can be formed, for example, as a chest airbag and / or a curtain type or curtain airbags. Such an airbag protects vehicle occupants from injuries in the shoulder or head region, in particular in the event of a side collision. In principle, however, it is conceivable that the airbag may injure vehicle occupants during inflation or deployment in the inflation region, for example, by sharp objects, sharp edges, protrusions or the like. In order to avoid this, it may be desirable in some cases for the vehicle-side surroundings of the inflation region or the placement of the airbag to be adjusted acc...
